Behaviour of prestressed box beam strengthened with CFRP under effect of strand snapping
The study aims to evaluate behaviour of a prestressed box beam strengthened with the Carbon Fibre Reinforced Polymer (CFRP) under the snapping of prestressed strands. Three external prestressed box beams are tested until failure. The evaluation focuses on the load carrying capacity, cracks pattern a...

| description | The study aims to evaluate behaviour of a prestressed box beam strengthened with the Carbon Fibre Reinforced Polymer (CFRP) under the snapping of prestressed strands. Three external prestressed box beams are tested until failure. The evaluation focuses on the load carrying capacity, cracks pattern and width, and torsional capacity of the beam. The results show that the use of CFRP causes significant reduction of beam deflection and an increase of its loading capacity under snapping effects. The cracks do not appear at the bottom of the beam where the CFRP is placed, and the torsion stiffness of the beam increases considerably. |
